Abstract

Ferritic-martensitic 12Cr-MoWSiVNbB (EP-823) steel was irradiated with 7 MeV Ni++ ions within fluence interval 5 × 1018−5.4 × 1019 ions/m2 and with 30 and 70 keV He+ ions within fluence interval 1020–1021 ions/m2 at 500°C. Results from a comparative analysis of Cr and Si radiation-induced segregation profiles near the surface are presented. Dependence of the amount of surface segregation on damage dose, displacement generation rate, and radiation-induced point defects concentration is established.
